I really enjoy the co-op modes and would love to see a a free roam game mode or two. It could be a survival based mode with your friends or build up your clans fortress to build and repair airships. it could open up to allow more then 4 people on one ship, or on a base where they work to defend , repair, upgrade, and replenish ammo for it and your ship(s). maybe building up your clan base would allow for your clan to gather more resources for your clans faction.
